with it l 'fs eemcaum Letters ltatent. est i es rm go 'Hiitfitatitiii at; January men. attractant subject of the Emperor of Japan, and a resident of East Pittsburgh, in the county of Allegheny and State of Pennsylvania ave invented a new and useful Improvement in Vapor Electric Devices, of which the following is a specification.

My invention relates to vapor electric apparatus, and it has for its object to provide a cup or container, for the mercury or'other vaporizahle' electrode of such apparatus, which shall be so constructed as to prevent the completion of an electrical connection of the vaporizahle electrode with parts external to the cup or container when the con doused vapor of the electrode overflows into the cup. v

Figure 1 of the accompanying drawing is a vertical sectional view through a part of a rectifier that embodies my invention, and Fig. 2 is a sectional view of a part of the container along the line H H of Fig. 1.

The cup or container 1 constituting the present invention isadapted for use in vaper electric apparatus, such as rectifying devices having iron'or other metallic or conducting casing 2 upon the bottom of which the cup or container rests, a suitable amount of space being left between the sides of the cup and the sides of the container into which condensed vapor of the mercury drains and in which it is collected. The cup or container 1 is preferably composed of quartz, porcelain or some other suitable in sulating material in order that the mercury 4:, which it contains and which constitutes the vaporizable electrode may be insulated from partsexterior thereto. The mercury within the cup is adapted to he connected to a circuit by means of a lead 5 that extends into the same and is surrounded by an insulating sleeve 6. Mercury that collects in the space surrounding the cup is edmitted to the interior of the cup throtig'li a notch or inlet '2 .whenever it attains a height slightly shove the said inlet which is located at a suitable distance, below the top' of the cup. The inlet 7 may, if desired, be an aperture in the cup near its top or any other means for causing the mercury to flow into the cup only at predetermined points and more y "thanofiehiayhe pressed sreruttiyttum Be it known that I, Ynsunneo SK'KELn aenter the cup through the inlets, they fail upon the crests of the lugs 8 and arethereby divided and. deflected, part to the right and part to the left, and as the streams leave the lugs 8, they fell upon the crests oi? the lugs 9 and 10 and are again divided. and deflected thereby Thus, the streams of mercury flowing into the cup are eilfectually broken up, so that they cannot provide continuous electrical paths between the mercury Within the cup and that which is outside of it I claim as my invention:

LA vapor electric device comprising? a casing, a vaporizahle electrode and an e. ectrode-contaihing cup having an inlet'iind internal means located below the inlet for interrupting the inflow of condensed vapor,

2. A vapor electric device comprisinu a casing, a vaporize-hie electrode and an e co trod s-containing cup rovided with an inlet arrier below the inlet and with an internal having an upper surface which. is inclined downwardly/in opposite directions there from.

3 A vapor electric device comprising a casing, a vaporizahle electrode and an electil trode-containing cup having an inlet and a plurality of superposed and staggered internal. barriers hclowthe inlet.

4. A vapor electric device comprising a casing, a vaporizable electrode and an. electrode-containing cup provided with aninlet and with a plurality of superposed and stag gored internal hnu'iers below the inlet having upper surfaces which are inclined down- Wardly' in opposite directions irom intermediate points thereof.

5. A vapor electric deviceeomprising a casing, a vaporizahle electrode, and a cup within the casing for the vaporizable electrode having means for directing thereinto condensed vapor of-the said electrode and for attenuating and breaking streams thereof.

'6. A vapor electric device comprising a metal casing, a vaporizable electrode and an insulating electrode-containing cup having an inlet and a plurality of superposed and staggered internal'barriers below the inlet.-

7. A vapor electric device comprising a metal casing, a vaporizable electrode and. an

insulating electrode-containing? cup having an inlet and internal means oeated below the inlet for interrupting the inflow of con- 15 clensed vapor. i

In testimony whereof, I have hereunto subscribed my name this 30th day of Dec. 1910. v
